Basics

Description

Fluid accumulation in the tissue and air spaces of the lungs causing impaired gas exchange and respiratory failure due to either failure of the left ventricle to remove blood adequately from pulmonary circulation or to an injury to the lung parenchyma or vasculature of the lung leading to inflammation and impaired gas exchange

Cardiogenic:

Abnormality in cardiac function leading to inadequate removal of fluid from the pulmonary circulation and inadequate tissue perfusion

May be assessed by echocardiogram

Most frequent cause of pulmonary edema

Noncardiogenic:

Increased alveolar–capillary membrane permeability and accumulation of fluid in the alveoli without a cardiac etiology
